11.10. DYNAMIC SET POINT

The regulator can be used to modify the
set point automatically, in accordance
with the outside conditions.
modification is achieved by subtracting
a value from the set point; this value
depends on the outside air temperature
measured by probe S2.
The binary parameter H33=1-0 can be
used to enable/disable the Dynamic set
point function.
The dynamic set point is only active in
HP operation mode.
The following parameters need to be
defined for the dynamic set point:
• H34 Balancing line
between 0.5 and 2)
• H35 Outside air temperature above
which balancing begins
between 15 and 25)
• H36 Range of outside air on which
the set point functions
between 5 and 10)
EXAMPLE:
When the set point is enabled (H33=1), three situations may arise:
-1st Case T.air <= H35 In this case the dynamic set point = Ut1
-2nd Case H35 < T.air < (H35+H36) In this case the dynamic set point = Ut1-[(T.air-H35)*H34]
-3rd Case T.air > (H35+H36) In this case the dynamic set point = Ut1-[H36*H34]
